ENGINEERING DEVELOPMENTS IN THE USSR; FROZEN CONCRETE FOR ROAD CONSTRUCTION

A NEW CONCRETING METHOD IN COLD WEATHER BASED ON THE PRINCIPLE THAT THE FRESH CONCRETE PLACED IN POSITION SHOULD BE FROZEN BEFORE THE INITIAL SETTING TAKES PLACE IS PROPOSED IN AN ARTICLE PUBLISHED IN THE SEPTEMBER 1969 ISSUE OF "AVTOMOBILNYIE DOROGI." THE AUTHORS, M. I. KHIGEROVICH, N. I. MUSHTAEVA AND M. C. KARASEV, CARRIED OUT RESEARCH WORK IN THE V. V. KUIBYSHEV CIVIL ENGINEERING AND STRUCTURAL INSTITUTE, MOSCOW. THE METHOD WAS FIRST TESTED IN FEBRUARY 1968. THE TEMPERATURE OF THE CONCRETE AT THE TIME OF PLACING VARIED FROM +3 C TO +8 C AND FREEZING STARTED 30-60 MINUTES LATER. AS SOON AS THE CONCRETE WAS FROZEN IT WAS COVERED WITH A LAYER OF SAND 5-7 CM THICK AND THE TRAFFIC WAS ALLOWED TO PASS OVER THE SLAB. AT THE END OF APRIL THE AVERAGE STRENGTH OF CONCRETE WAS ABOUT 200 KG/SQUARE CM AND THE SAND WAS REPLACED WITH THE BITUMEN MACADAM SURFACE. AFTER 18 MONTHS USE, THE ROAD IS IN GOOD CONDITION.
